Magnetic door contact failure

[morg]

Hi guys, is it common for them to fail? I got these 10 contacts from TLC, 2 have failed so far. Now I'm worried about the others.

The worse thing is that they have failed/stuck in the NC position, which would mean if a door was breached the alarm would not go off... And the alarm panel would give no errors (when setting the alarm).

Thanks

It happens ... once had a bag of 20 from gardtec fitted a new build ...changed most of them on alarm handover !
